module ActionController # :nodoc:
|
||||
# Represents an HTTP response generated by a controller action. One can use
|
||||
# an ActionController::Response object to retrieve the current state
|
||||
# of the response, or customize the response. An Response object can
|
||||
# either represent a "real" HTTP response (i.e. one that is meant to be sent
|
||||
# back to the web browser) or a test response (i.e. one that is generated
|
||||
# from integration tests). See CgiResponse and TestResponse, respectively.
|
||||
#
|
||||
# Response is mostly a Ruby on Rails framework implement detail, and
|
||||
# should never be used directly in controllers. Controllers should use the
|
||||
# methods defined in ActionController::Base instead. For example, if you want
|
||||
# to set the HTTP response's content MIME type, then use
|
||||
# ActionControllerBase#headers instead of Response#headers.
|
||||
#
|
||||
# Nevertheless, integration tests may want to inspect controller responses in
|
||||
# more detail, and that's when Response can be useful for application
|
||||
# developers. Integration test methods such as
|
||||
# ActionController::Integration::Session#get and
|
||||
# ActionController::Integration::Session#post return objects of type
|
||||
# TestResponse (which are of course also of type Response).
|
||||
#
|
||||
# For example, the following demo integration "test" prints the body of the
|
||||
# controller response to the console:
|
||||
#
|
||||
# class DemoControllerTest < ActionController::IntegrationTest
|
||||
# def test_print_root_path_to_console
|
||||
# get('/')
|
||||
# puts @response.body
|
||||
# end
|
||||
# end
